For International Participation at ANS National and Topical Meetings
If you need to request a visa letter for any of the ANS Meetings, please contact registrar@ans.org
A citizen of a foreign country who seeks to enter the United States generally must first obtain a U.S. visa, which is placed in the traveler’s passport, a travel document issued by the traveler’s country of citizenship.
Certain international travelers may be eligible to travel to the United States without a visa if they meet the requirements for visa-free travel. (Note: U.S. citizens don’t need a U.S. visa for travel, but when planning travel abroad may need a visa issued by the embassy of the country they wish to visit. In this situation, when planning travel abroad, learn about visa requirements by country, see country information in the International Travel Section of this website.)
